[uml-devel] [PATCH] uml: fix hardcoded ZONE_* constants in zone setup

["Paolo 'Blaisorblade' Giarrusso" <blaisorblade@yahoo.it>]

From: Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it>

Remove usage of hardcoded constants in paging_init().

By chance I spotted a bug in zones_setup involving a change to ZONE_* constants,
due to the ZONE_DMA32 patch from Andi Kleen (which is in -mm). So, possibly,
instead of zones_size[2] you will find zones_size[3] in the code, but that
change is wrong and this patch is still correct.
